Know where to get plastic sheets ?

Basically I am starting a project here soon where
I'll need THIN sheets that will be at " least " two
feet in length and a foot and a half wide. They can
only be 1/16 or 3/32 inch thickness so I need something
STRONG that won't flex allot.. Any ideas out there ?

BTW, I would prefer to keep this as some type of plastic
as I will be shaping it and don't want to get into messing
with sheet metal... :confused

 

If you have a outdoor lighted sign shop in your area, stop by. The sometimes have scrap bins with numerous thicknesses and types of sheet plastic. .12" lexan came to mind but that is over your limitations. Might find a thin, non-flex in your dimensions. There are ton of plastics out there withe huge variation in characteristics and applications. I'd say as a general rule the more rigid a thin sheet of plastic is, the more brittle and unforgiving it is to tool work.

 

Just remebered.

Main reason I suggested the scrap bin is because most plastic sheeting other than local hardware store acrylic sheet or modelers styrene, must be purchased in 4x8 sheets.

Forgot these guys care plastic sheet cut to square foot sizes.
